Toallhuihom it may cohocrni y 4Be itgkn'own that I, MARION M. BARNES,

Va'citizen of'the UnitedStates,- residing at Lovilia, in the county ofMonroe, `State of iowa, have invented certain new and use# fulAImprovements in Motors; and I do hereby` declare the following to be afull, clear, and exact description' of the invention, such as willenable others skilled inthe art to which it' appertains to make and usethe same.' l A This invention relates to tractors such as are used onfarms, roads and other like placesfor hauling, plowing, cultivating andthe like.

The' principal object of the invention lis to improve the generalconstruction vofdevices of thisI character. A second object oftheinvention is to providean improved means for driving the front orsteering 4wheels of such an engine. 'A third object 'of the inventionis-'to provide (an improved steering mechanism for such an engine..

,With theabove and other' objects in view the invention consists in'general of certain novel details of 'construction and combina.-t-ion'offparts lhereinafter fully described,

lillust'rzjited inthe accompanying drawings,l

and. specifically claimed.

, In the accompanying drawings, like chan' acters of reference indicatelike parts in the several views, and Figure 1 is a plan view oi thetractor constructed in accordance with `this inventlon. Fig. 2 isasection on v the line 2-2 of Fig. 1. Fig. 3 is a section on the line3-3 of Fig. 2. Fig. 4 is a view of theinterior of one 'of the drivingWheels. Fig. 5 is an enlarged detail showingone of the steering gearsremoyedfrom thev apparatus. Fig. 6 is a detail section on the line til-6of Fig. 1. Fig. 7 isadetail elevation ci one oit the steering axles.. Fi

3 is a detail plan of the axle shown in Fig.`

- In carrying out the Vobjects of this invention'there is provided aframe 10 which 1s supported on the rear axles 11 mounted suitablybeneath :the frame and carrylng the ground wheels 12).v ,Across thefront of the frame extendsan I-beam 13 which has its ends cut away asiat14 so that a Z-shaped bracket 15 may be' attached tothe upper flange ofthe beam at each end .and .overhangth'e same as clearly seen 1n Fig. 2.The leder ange of the I-beam is provided with a circular opening which1s 1n detail At 16 is a vertical shaft which is square 1n cross sectionand is providedlwithcylindrical joint-s 17 fittedin the opening in thebracket vand I-beamand similar openings at the opposite end ofthe-beam.` Projecting from each of the vertical shafts '16 is a stub`axle '1'8 Whereon is revolubly'mounted-a tractor whe'el19. By meansof'this arrangement the. tractor wheel may lswing bodily about.. theaxis of thel shaft 16 and in rear to permit such swinging movement thefront of the frame fis connected to alinement with asimilar opening inthe over- .hanging part of the respective bracket 15.

the beam 13 by. a narrow neck 19 formed by curving the' frame membersinward as at 20. By means of this arrangement the tractor wheels may becaused'to assume the position shown in dotted lines in Fig. 1.

The frame 10 is covered with the usual platform'21 and onthis'platt'ormiis mounted an engine 22 provided lwith a shaft 23.

()n this shaft 23 is a bevel pinion 24 which meshes with a bevel gear.25 ormin part of the .usual '.diiierential gearing in 'cated in generalat A26. Extending from the different-ial gearingware the alined shafts27 which are supported in the vertical portions of the bracketsandinbearings 28185 on the beam 13. On each of these shafts 27 is apinion 29 which meshes with an idler 30 carried on the respective`vertical shaft 16. This pinion 3Q meshes with a gear ring 31 on therespectivetraction wheel l19.

At' 32 is a segmental bevell gear whichis provided with a hub 33 havingan open ended slot 34 therein so that this Ahub can be slipped over therespectiveshaft 16 and -held when positioned thereon by a pin; 35.

Mounted in suitable bearings 36 on the beam 13- is a shaft 37 which isprovided with pinionjs 38 meshing respectively with the segmental gears32.

From an inspection of Fig. 2Iit will bel lseen that one of these pinionsmesh. with a gear arranged above it while the other meshes with a geararranged below it so that the rotation of the shaft 37 will move theground wheels 19 in such manner thatthey will 'at .e all times remainparallel. On the shaft 37 is a worm wheel 39 and extendinglongitudinally o f the machine in an upwardly steering post 40whereon isa worm 41 which meshes with the worm upper end' ofthis steering post isaste'ering and rearwardly directionjis afwheel-'139;'. On the Wheel 42located conveniently to the diivers Sezze 43. 'in the 'operation of thisdevice iz will .be plain. that when *che engine is un.
